Pre-Installation Considerations
Pre-Installation Checklist
Complete the following checklist before beginning unit installation.
Verify the unit size and tagging with the unit nameplate.
Make certain the floor or foundation is level, solid, and sufficient to support the unit and accessory weights. Level or repair the floor before positioning the unit if neccesary.
Allow minimum recommended clearances for routine maintenance and service. Refer to unit submittals for dimensions.
Allow three fan diameters above the unit for the discharge ductwork. Return air enters the rear of the unit and conditioned supply air discharges through the top.
Electrical connection knockouts are on the top, left side of the unit.
Allow adequate space for piping access and panel removal. Condenser water piping, refrigerant piping, and condensate drain connections are on the lower left end panel.
Electrical supply power must meet specific balance and voltage requirements as described in the “Electrical Requirements” section.
Receiving and Handling
Shipping Package
Midrange units ship assembled on skids. Units ship assembled, piped, and charged with either R410a (model SCWH)
or a dry nitrogen charge (model SCRH).
Receiving Checklist
Complete the following checklist immediately after receiving unit shipment to detect possible shipping damage.
Inspect individual cartons before accepting. Check for rattles, bent carton corners, or other visible indications of shipping damage.
If a unit appears damaged, inspect it immediately before accepting the shipment. Make specific notations concerning the damage on the freight bill. Do not refuse delivery.
Inspect the unit for concealed damage before it is stored and as soon as possible after delivery. Report concealed damage to the freight line within the allotted time after delivery. Check with the carrier for their allotted time to submit a claim.
Do not move damaged material from the receiving location. It is the receiver’s responsibility to provide reasonable evidence that concealed damage did not occur after delivery.
Do not continue unpacking the shipment if it appears damaged. Retain all internal packing, cartons, and crate. Take photos of damaged material if possible.
Notify the carrier’s terminal of the damage immediately by phone and mail. Request an immediate joint inspection of the damage by the carrier and consignee.
Notify your Trane representative of the damage and arrange for repair. Have the carrier inspect the damage before making any repairs to the unit.
Unit Storage
Take precautions to prevent condensate from forming inside the electrical compartments and motors if the unit is stored before it is installed.
Service Access
Maintain adequate clearances around and above the unit to ensure proper unit operationa nd allow sufficient service accesss. Trane recommends
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure power cannot be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.
Installation Preparation
Before installing the unit, perform the following procedures to ensure proper unit operation.
1.Verify the floor or foundation is level. Shim or repair as necessary. To ensure proper unit operation, install the unit level in both horizontal axes.
2.Allow adequate service and code clearances as recommended in “Service Access” section. Position the unit and skid assembly in its final location. Test lift the unit to determine exact unit balance and stability before hoisting it to the installation location. See the “Proper Lifting Procedure” section for proper rigging procedures and cautions.
3.Remove the skids from under the unit. If you find internal damage, file a claim immediately to the delivering carrier.
4.Remove the protective shipping covers from the unit.
5.Verify the compressor isolator shipping brackets are removed and the isolators are properly tightened for operation.
